Currently data channel protection is only available for implicit TLS. This can also be required by FTP servers in explicit TLS mode (e.g. QuFTP on QNAS devices even don't allow to configure or disable that).
With my changes, the default behavior is still the same but there is now an additional option to enable data channel protection for explicit TLS.
